Knee joint focal cartilage prosthesis and mounting method and mounting kit thereof

The invention provides a knee joint focal cartilage prosthesis and an installation method and an installation suite thereof, the knee joint focal cartilage prosthesis is made of polyether-ether-ketone materials, the knee joint focal cartilage prosthesis comprises a first end and a second end which are oppositely arranged, the first end is provided with an arc-shaped surface, the second end is provided with at least one connecting column, and the arc-shaped surface is provided with an arc-shaped surface; a plurality of convex ribs are convexly arranged on each connecting column in the extending direction, and the surface, far away from the first end, of each connecting column contains at least one of hydroxyapatite, titanium and tantalum. By means of the structure and the materials, the fixing effect of the prosthesis in subchondral bone is enhanced, the prosthesis can provide a smooth joint surface after being implanted, friction and abrasion are reduced, a patient is helped to rapidly recover the joint funct
